Title: Test equipment protection circuit for telephone branch exchanges - has automatic blocking of test unit output if high voltage appears at test object
Inventor: GLAS JOSE
IPC: H04M3/22
Filed: 1980-12-11
Abstract: The circuit gives adequate protection of the test equipment without the need for buffer resistors of high ohmic value. The protection circuit is used for connection between the test equipment and the apparatus under test. The inputs from the test equipment (GA1'-GAx') generate a voltage low to carry out the test function. They are connected via gates (I....IV), switching transistors (T1...Tx), and buffer resistors (R5-R8) to a diode network. The connection (GA1...GAx) from the apparatus under test come to the same network, which is also connected to a comparator (VG). The comparator has two differential amplifiers (V1,V2). One (V1) has one input (a) connected via diodes (D5-D8) to receive positive voltages, and the other (b) is connected to a positive reference. The other amplifier (V2) is similarly connected (D9-D12) for negative voltages (b') with a negative reference (a'). If the reference voltage is exceeded on either amplifier, signifying the existence of a voltage greater than 12V, an output results which triggers an OR-gate (OG). In turn this causes the transistors (T1-Tx) to turn off, thus protecting the test unit. Buffer resistors (R5-R8) need only be sized for 12V operation.

Patent DE-3129177-A1 (DE)
Title: Cableway, so-called Blondin
Inventor: GALLUZZI FRANCESCO ANTONIO
IPC: B66C21/02
Filed: 1981-07-21
Abstract: The present invention relates to a cableway, a so-called "Blondin". As is generally known, the pivoting movement of the towers of a "Blondin" takes place with the use of two winches which carry a cable extending from the top end of the tower. These winches are conveniently arranged at a distance from the tower. In many cases, e.g. when the ground is very steep, the arrangement of these winches is exceptionally difficult. The object of the invention is therefore to solve this problem and create a cableway whose tower (10) has an essentially triangular configuration and consists of a long stanchion (11) and a short stanchion (14), the short stanchion (14) being linked to the top end of the long stanchion (11) and being fastened at the bottom to the foundation (12) by means (16, 19; 31, 50) of variable length. <IMAGE>

Title: Idling stage for internal combustion engines
Inventor: BAYER PETER
IPC: F02M3/045
Filed: 1981-09-18
Abstract: An idling stage for internal combustion engines is proposed, in which a throttle valve arranged in an intake pipe of the internal combustion engine is bridged by a bypass duct and a valve (14) is located in the bypass duct, by means of whose axially guided valve plug (15) the bypass duct can be closed. In order to be able to open the valve (14) even when the engine is running and the throttle valve is closed, if the force acting on the valve plug due to the intake pipe pressure is particularly great, the valve plug (15) and a valve axis (22) causing axial guiding of the plug (15) have a bore passing through them and the bore (28) opens into a closed space (26) for equalising the pressure inside the valve. By means of this idling stage, an idling control can be achieved in that the valve closes in excess of the idling speed and opens below the idling speed. <IMAGE>
